“Off The Main Thread”

10.9.2019
JavaScript is what they call "single-threaded." As Brian Barbour puts it: This means it has one call stack and one memory heap. We all feel a symptom of that regularly in the form of performance jank and non-interactivity on elements or entire sites. If we give JavaScript lots of jobs and it gets...

Lazy load embedded YouTube videos

20.8.2019
This is a very clever idea via Arthur Corenzan. Rather than use the default YouTube embed, which adds a crapload of resources to a page whether the user plays the video or not, use the little tiny placeholder webpage that is just an image you can click that is linked to the YouTube embed. It still...

CSS Grid is mostly composed of rows, columns, cells, tracks, gaps etc. These things are not elements by themselves; hence, it can be really tasking to visualize and debug them. In this post, we’ll

Haunted: Hooks for Web Components

3.7.2019
I was just chatting with Dave and he told me about Haunted. It's hooks, but for native web components! Pretty cool. I think the existence of stuff like this makes using web components more and more palatable — particularly in that totally-native no-build-step-needed-at-all kinda way. I...

Tips for rolling your own lazy loading

1.7.2019
You may have heard (or even issued the call) that “we can just use lazy loading!” when looking for a way to slim down a particularly heavy web page. Lazy loading is a popular technique for gradually requesting images as they come into view, rather than all at once after the HTML of the page...
